Abstract: La présente invention concerne un appareil (20) permettant de traiter du sang de mammifère afin de l'utiliser ultérieurement dans une procédure médicale. Cet appareil comprend un coffret (21) placé dans un environnement sûr et une porte (26) assurant l'accès à cet environnement. Un système d'entrée est prévu pour transporter une charge de sang à partir d'une source vers le coffret (21) et un flacon (56) est placé de manière amovible dans l'environnement sûr et couplé au système d'entrée de charge pour recevoir cette charge. Des éléments d'application de contraintes (86, 88) sont couplés au coffret (21) et positionnés de manière à permettre le traitement de la charge dans le flacon (56). Un système de sortie est couplé au flacon et comprend un récepteur (52) pour la charge traitée. Cet appareil (20) comprend un système de commande automatisé (151) pouvant fonctionner lors de la fermeture de la porte (26) pour verrouiller la porte puis traiter la charge, et provoquer ensuite le déplacement de la charge depuis le flacon jusqu'au récepteur. Par conséquent, une charge provenant du système d'entrée est traitée et fournie au récepteur. La porte est ensuite débloquée et la charge traitée peut être retirée et utilisée pour terminer la procédure médicale. L'invention concerne également un ensemble de flacons (48)  prévu pour être utilisé dans l'appareil et un procédé d'utilisation.

Title: Procede et systeme de quantification vectorielle multi-debit en treillis d'un signal
Inventor: BESSETTE BRUNO
IPC: G10L19/038
Filed: 2003-05-30
Abstract: La présente invention concerne un procédé et un système de
quantification vectorielle multi-débit en treillis d'un vecteur source
x représentant une trame à partir d'un signal de source à
utiliser, par exemple, dans des systèmes de transmission et de stockage numériques.
Le procédé de codage de quantification multi-débit en treillis
comprend les étapes consistant à associer à x un point de treillis
y dans un treillis non délimité Λ; à vérifier si
y est inclus dans le code de base C dérivé du treillis Λ; ensuite,
si tel est le cas, à indexer y dans C de manière à obtenir des indices
de quantification. Sinon il consiste alors à étendre le code de base
à l'aide, par exemple, d'un procédé d'extension
fondé sur Voronoi, produisant un code étendu; à associer à
y un vecteur de code C provenant du code étendu, et à indexer y dans le
code étendu C. La technique d'extension consiste à obtenir
des codes à débit supérieur à partir des codes de base comparée
au procédé et au système de quantification selon l'état
de la technique.

Title: Transgenic mice for the analysis of hair growth
Inventor: MCNAB ALISTAIR R
IPC: C07K14/47
Filed: 1989-11-29
Abstract: TRANSGENIC MAMMALS FOR THE ANALYSIS OF HAIR GROWTH             ABSTRACT This  invention  is  a  transgenic,  non-human  mammal  having  a recombinant transgene  comprising a promoter sequence from a gene which codes for a hair specific protein and a reporter gene.  This recombinant gene is introduced into the animal, or an ancestor of the animal, at an embryonic stage.  Hair specific proteins are expressed by skin cells during the hair growth cycle. Reporter genes are genes for which expression is detectable.   The transgenic animal of the present invention will express the reporter gene when induced under the control of the regulatory mechanisms for hair growth present in the  animal.   Consequently,  the  transgenic  animal of the present invention provides a system to study regulation of genes related to hair  growth  and  a  system  which  provides  tissue  specific,  time specific limits on expression of structural transgenes.

Abstract: 22 Text (indicia, words, symbols, etc.) of documents (10) is highlighted in such a way that it will reproduce when electronically copied (e.g. photocopied or telecopied). This is accomplished by applying a tone (17) to only that area of the document to be highlighted and so that the tone remains in place during copying. The tone is sufficiently dark so as to highlight the text, but light enough so that the text is readable. The tone may be a dot or line screened tone having about 30-65 lines per inch with a density of about 10-22%. The tone may be applied on adhesive tape (15) and just placed over the document portions to be highlighted. The tape may be dispensed from a dispenser (24). Alternatively the tone may be on a transfer sheet (52, 152), and is transferred to the document merely by the act of rubbing on the transfer sheet. The tone may also be applied to the document utilizing a print wheel (63, 163) in a casing (62, 162), that is moved over the document. After the document is electronically copied (e.g. by a photocopier or a facsimile machine, for example) the document is highlighted yet the text is clearly legible.

Title: Image recording method
Inventor: OBATA HIROYUKI
IPC: G11C7/00
Filed: 1990-03-15
Abstract: ABSTRACT      Electric discharge between a photosensitive member and a charge retaining medium is ON/OFF controlled by changing either the gap or the gas pressure between these two members, so that it is possible to effect image recording in a state where a DC voltage is being applied.  Accordingly, it is possible to effect image recording on the charge retaining medium without the need for precise control for obtaining a high-voltage pulse and without employing an optical shutter.  In addition, an electric charge that is emitted by a field is attracted to the charge retaining medium and accumulated on the surface thereof, thereby forming an electrostatic latent image, and thus making it possible to attain image recording of extremely high resolution.     Further, the conductive layer and/or surface of at least either the photosensitive member or the charge retaining medium is provided with dimple patterns, thereby dimply changing the voltage that is applied across the gap between them and modulating the discharge pattern in accordance with the dimple patterns, and thus enabling recording of a halftone dot image simultaneously with the exposure.  It is therefore unnecessary to effect a special electrical processing for the formation of halftone dots and hence possible to record a halftone dot image at a reduced cost and with ease.     Further, an electric charge which is opposite in polarity to an image forming charge is uniformly formed on the charge retaining medium in advance of the image exposure, and thereafter image exposure is carried out, thereby reducing the background potential at the unexposed region and increasing the contrast potential of the electrostatic latent image formed on the charge retaining medium.  In addition, it is possible to increase the voltage distribution to the photosensitive member.  As a result, it is possible to improve the photosensitivity of image exposure.
